Grundfos CRNE 15 Variable-Speed Pump, 2 in ANSI, 4000 rpm

Description GRUNDFOS · VARIABLE-SPEED VERTICAL MULTISTAGE PUMP CRNE 15 — 2 in ANSI, 4000 rpm Variable-speed vertical multistage centrifugal pump in 316 stainless steel with a Grundfos MLE motor and built-in frequency converter. 8 models from CRNE 15-1 to CRNE 15-10, 2 to 25 HP, 2 in ANSI ports, 4000 rpm version, with or without a factory pressure sensor. 81-836 ft (35-362 PSI) Max Head · 122-142 GPM Max 2-25 HP 200-240V 1Ph (2 HP) · 200-240V 3Ph · 440-480V 3Ph 2 in ANSI Ports In-Line Suction and Discharge Grundfos MLE Motor, Built-In Drive Up to 4000 rpm 363 PSI Max Operating Pressure NSF/ANSI 61 95-329 lb Weight Overview The CRNE 15 is the CRN 15 pump end on a Grundfos MLE motor with the frequency converter built in, so the pump varies its own speed to hold a setpoint instead of running flat out against a throttled valve. Every part in contact with the liquid is high-grade stainless steel (EN 1.4401, AISI 316). This listing is the 4000 rpm version with 2 in ANSI connections; Grundfos sells the 4000 rpm and 3600 rpm versions as separate part numbers with different curves, so each is listed on its own. The Grundfos nominal duty is 92.2 to 109 GPM by model at full speed; size it from the performance table below. 8 models, CRNE 15-1 to CRNE 15-10, 2 to 25 HP; some models are offered on two motor sizes, and the larger motor holds the full-speed curve further out Supply: 200-240V 1Ph (2 HP), 200-240V 3Ph, 440-480V 3Ph Every model with or without a pressure sensor; sensor range 0-145 psi, 0-232 psi, 0-362 psi, 0-580 psi by model 2 in ANSI flanges MLE motor: IE5 efficiency class, IP55, speed range 360 rpm to rated speed, graphical control panel; HQQE (EPDM) cartridge shaft seal What Ships and What It Needs to Run Included: the CRNE 15 pump end and its Grundfos MLE motor with built-in frequency converter, factory-assembled as one complete pump. With-sensor versions come with a pressure sensor in the range shown for the model. ANSI companion flanges required, ordered separately. Grundfos supplies the companion connection as a separate flange set: two flanges, two gaskets, nuts and bolts, sized 2 in. Without-sensor versions: for constant-pressure control, add a sensor or an external control signal. Suction and discharge piping, valves, power supply and disconnect: sized to your system and ordered separately. Genuine Grundfos equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier. Warranty: 24 months from date of installation, but not more than 30 months from date of manufacture (Grundfos limited warranty). Grundfos repairs or replaces its own product; costs of removal, installation and transportation are not covered, and products sold but not manufactured by Grundfos carry their own manufacturer’s warranty.

Find the pressure you need at your flow and pick the first model that reaches it at full speed; the drive then slows the pump to hold your setpoint. Pressure at flow in PSI, one row per model and motor.

Shut-off is Grundfos’s published maximum head. Flow columns are read from the 100% speed curve on the Grundfos 60 Hz chart for each model and motor (water at 68 °F), digitized and rounded down, at 20%, 50% and 75% of 120 GPM, the last regular flow every curve in this listing reaches; the curves end at 122 to 142 GPM. Where a model is offered on two motor sizes, the smaller motor reaches its power limit sooner and its curve falls away at high flow. At reduced speed the pump runs on a lower curve; full Grundfos charts with the reduced-speed curves are in the product images. Grundfos’s published duty point sits above its own curve by more than 3% of shut-off on CRNE 15-10 (20 HP), CRNE 15-8 (15 HP), CRNE 15-5 (10 HP), CRNE 15-4 (7 1/2 HP), CRNE 15-1 (2 HP) (by up to 70 ft at the rated flow), where the motor’s power limit cuts the curve; the table follows the curve. Well & Irrigation CalculatorTank Calculator Before You Buy — The Limits That Decide the Fit Check What decides the fit Duty point The model’s full-speed pressure at your flow must cover the system’s total head; shut-off is the most it can make, at zero flow. Working pressure Inlet pressure plus the pressure the pump adds must stay within the maximum operating pressure: 363 PSI. Sensor For constant-pressure control order the with-sensor version, and pick a sensor range above your setpoint; without-sensor versions need a sensor or external control signal for that. Power Supply at the voltage and phase shown in the selected option; the drive is inside the motor, so no separate VFD is needed. Connections ANSI companion flanges (2 in) ordered separately. Liquid temperature −4 °F to 248 °F, HQQE (EPDM) shaft seal. Applications Constant-pressure water supply and boosting, HVAC heating and cooling circulation, industrial water supply and transfer, process liquids, wash and clean, water treatment and irrigation (Grundfos CR range applications).
